我们为用户使用Symfony2框架和FOSUserBundle.所以我们拥有自己的UserBundle,它继承自FOSUserBundle.

问题是：当我们发送表单以使用错误的密码编辑用户时,标题中显示的app.user.username会因为表单不正确而更改.然后,当我们重新加载页面时,app.user.username具有正常的用户名(因为它在数据库中没有更改).问题是,为什么app.user.username会暂时更改我们刚用密码错误发送的表单(编辑用户)的值？

我们使用FOSUser的正常路由：

fos_user_security:
    resource: "@FOSUserBundle/Resources/config/routing/security.xml"

fos_user_profile:
    resource: "@FOSUserBundle/Resources/config/routing/profile.xml"
    prefix: /profile

fos_user_register:
    resource: "@FOSUserBundle/Resources/config/routing/registration.xml"
    prefix: /register

fos_user_resetting:
    resource: "@FOSUserBundle/Resources/config/routing/resetting.xml"
    prefix: /resetting

fos_user_change_password:
    resource: "@FOSUserBundle/Resources/config/routing/change_password.xml"
    prefix: /profile

和FOSUser的默认控制器：

public function editAction(Request $request)
{
    $user = $this->getUser();
    if (!is_object($user) || !$user instanceof UserInterface) {
        throw new AccessDeniedException('This user does not have access to this section.');
    }

    /** @var $dispatcher \Symfony\Component\EventDispatcher\EventDispatcherInterface */
    $dispatcher = $this->get('event_dispatcher');

    $event = new GetResponseUserEvent($user, $request);
    $dispatcher->dispatch(FOSUserEvents::PROFILE_EDIT_INITIALIZE, $event);

    if (null !== $event->getResponse()) {
        return $event->getResponse();
    }

    /** @var $formFactory \FOS\UserBundle\Form\Factory\FactoryInterface */
    $formFactory = $this->get('fos_user.profile.form.factory');

    $form = $formFactory->createForm();
    $form->setData($user);

    $form->handleRequest($request);

    if ($form->isValid()) {
        /** @var $userManager \FOS\UserBundle\Model\UserManagerInterface */
        $userManager = $this->get('fos_user.user_manager');

        $event = new FormEvent($form, $request);
        $dispatcher->dispatch(FOSUserEvents::PROFILE_EDIT_SUCCESS, $event);

        $userManager->updateUser($user);

        if (null === $response = $event->getResponse()) {
            $url = $this->generateUrl('fos_user_profile_show');
            $response = new RedirectResponse($url);
        }

        $dispatcher->dispatch(FOSUserEvents::PROFILE_EDIT_COMPLETED, new FilterUserResponseEvent($user, $request, $response));

        return $response;
    }

    return $this->render('FOSUserBundle:Profile:edit.html.twig', array(
        'form' => $form->createView()
    ));
}

以下是标题中显示的代码部分,在使用错误的密码提交表单时不应更改. (app.user.username)

<ul class="nav navbar-nav navbar-right">
    {% if is_granted("IS_AUTHENTICATED_REMEMBERED") %}
    <li>
        <a href="{{ path('fos_user_profile_show') }}">{{ app.user.username }}
        </a>
    </li>
    <li>
        <a href="{{ path('fos_user_security_logout') }}">
                {{ 'layout.logout'|trans({}, 'FOSUserBundle') }}
        </a>
     </li>
     {% else %}
     <li>
        <a href="{{ path('fos_user_registration_register') }}">{{ 'layout.register'|trans({}, 'FOSUserBundle') }}</a>
     </li>
     <li>
        <a href="{{ path('fos_user_security_login') }}">{{ 'layout.login'|trans({}, 'FOSUserBundle') }}</a>
      </li>
      {% endif %}
</ul>

以下是显示的公式代码：

<div class="well">

{{ form_start(form, {'attr': {'class': 'form-horizontal'}}) }}

{{ form_errors(form) }}

<div class="form-group">
  {# Génération du label username. #}
  {{ form_label(form.username, 'register.form.username'|trans, {'label_attr': {'class': 'col-sm-3 control-label'}}) }}

  {# Affichage des erreurs pour ce champ précis. #}
  {{ form_errors(form.username) }}

  <div class="col-sm-4">
    {{ form_widget(form.username, {'attr': {'class': 'form-control'}}) }}
  </div>
</div>

  <div class="form-group">
  {# Génération du label adresse. #}
  {{ form_label(form.address, 'register.form.address'|trans, {'label_attr': {'class': 'col-sm-3 control-label'}}) }}

  {# Affichage des erreurs pour ce champ précis. #}
  {{ form_errors(form.address) }}

  <div class="col-sm-4">
    {{ form_widget(form.address, {'attr': {'class': 'form-control'}}) }}
  </div>
</div>

  <div class="form-group">
  {# Génération du label nom du contact. #}
  {{ form_label(form.contactName, 'register.form.contact_name'|trans, {'label_attr': {'class': 'col-sm-3 control-label'}}) }}

  {# Affichage des erreurs pour ce champ précis. #}
  {{ form_errors(form.contactName) }}

  <div class="col-sm-4">
    {{ form_widget(form.contactName, {'attr': {'class': 'form-control'}}) }}
  </div>
</div>

  <div class="form-group">
  {# Génération du label email. #}
  {{ form_label(form.email, 'register.form.email'|trans, {'label_attr': {'class': 'col-sm-3 control-label'}}) }}

  {# Affichage des erreurs pour ce champ précis. #}
  {{ form_errors(form.email) }}

  <div class="col-sm-4">
    {{ form_widget(form.email, {'attr': {'class': 'form-control'}}) }}
  </div>
  </div>

  <div class="form-group">
  {# Génération du label numéro de téléphone. #}
  {{ form_label(form.phone, 'register.form.phone'|trans, {'label_attr': {'class': 'col-sm-3 control-label'}}) }}

  {# Affichage des erreurs pour ce champ précis. #}
  {{ form_errors(form.phone) }}

  <div class="col-sm-4">
    {{ form_widget(form.phone, {'attr': {'class': 'form-control'}}) }}
  </div>
  </div>

  <div class="form-group">
  {# Génération du label mot de passe. #}
  {{ form_label(form.current_password, 'register.form.password'|trans, {'label_attr': {'class': 'col-sm-3 control-label'}}) }}

  {# Affichage des erreurs pour ce champ précis. #}
  {{ form_errors(form.current_password) }}

  <div class="col-sm-4">
    {{ form_widget(form.current_password, {'attr': {'class': 'form-control'}}) }}
  </div>
</div>

{# Pour le bouton, pas de label ni d'erreur, on affiche juste le widget #}
{{ form_widget(form.saveButton, {'attr': {'class': 'btn btn-primary'},  'label': 'profile.edit.submit'|trans }) }}

{# Génération automatique des champs pas encore écrits.
 Dans cet exemple, ce serait le champ CSRF (géré automatiquement par Symfony !)
 et tous les champs cachés (type « hidden »). #}
{{ form_rest(form) }}

{# Fermeture de la balise <form> du formulaire HTML #}
{{ form_end(form) }}

</div>

这是我们用于此特定表单的FormType：

public function buildForm(FormBuilderInterface $builder, array $options)
{
    // add your custom field
    $builder->add('contactName', 'text')
            ->add('phone', 'text')
            ->add('address', 'text')
            ->add('saveButton', 'submit');
}

由于getParent()函数,FormType继承自ProfileFormType(FOSUserBundle中的Default).

感谢您的帮助,找出问题所在.我们不明白为什么app.user.username在标题中发生更改,因为表单是使用错误的密码发送的,并且数据库中的数据未更改,并且对于代码中的法语注释抱歉:).

最佳答案 这是通过设计发生的.在您调用$form-> handleRequest($request)时,用提交的表单数据更新用户实体.当您访问app.user时,您实际上正在访问同一个用户实体.
